\SOLU TION OF BENZOIC SULPHIONl-DE IN OILS, 86C- SPECIFICATION forming part of Letters Patent No. 410,940, dated September 10, 1889.

0 Application filed April 24, 1886- Serial No. 200,090. (No specimens.)

Toal whom it may concern-I Be it known that I, ADOiPH SOMMER, a

4 citizen'of the United States, residing at Berkeey, in the county of Alameda and State of California, have invented new and useful Mixtures of Benzoic Sulphio'niqle, it a certain class of ingestible carbon compounds; and I do hereby declare that the followingis a full, clear, and exactdesdription of theinvention, which will enable others skilled in cheiriical manipulations to apply and make the same.

He'retofore the use of benzoic sulphionide as a sweetening agent has been confined to such of the alimentary and medicinal substances as are soluble in water, while the sweetening of any of those alimentary, medicinal, and chewable carbon. compounds which are insoluble in Water, but soluble in bisulphide of carbon, has been accomplished only by the mechanical indorporation of either sugar, glycerine, or extract of licorice. I find, however, that this latter class of substances is capable, under certain conditions, of dissolving a small amount of benzoic sulphionil le, and that the sweetening of these bodies can be accomplishedjmuch better thanhas been done heretofore by treating them in the manner described-below. I i

In order to preparethese e'omposijions, I reduce the carbon compound, "or a mixture of such compounds, if. the same is not liquid at the prevailing temperature, by the aid of heat, or by means of a solvent, 01 both, to the liquid or plastic state. I then add of finelypowdered' benzoic sulphionide an amount sufficient to impart the desired degree of sweetness and thoroughly incorporate the powder by agitation. I continue the agitation, aided; if necessary, by heating, until the benzoic sulphionide is entirely or nearly dis solved. If the finished composition is to be transparent, I filter the mixture by any of the well-known devices suitable to the occasion. In the case of substances which are ordinarily liquid and which would be deteriorated by hcating-'-such as cod-liver oil and copaiba-l omit the heating altogether aiid bring about the combination 1) prolonged digestion at the prevailing temperature and frequent agitation. The combination of henzoic sulphionide with this class of bodies may also'be effected by dissolving the benzoic,

, and heating, the mixture with constant agitation until theoriginalsolvent has evaporated. Still another Way of accomplishing the same result, which, however is only applicable to those substances *iwhich are either liquid or readily liquefied, is to filter the liquid or liquefied substance that is to be sweetened through a layer of beuzoi'c sulphionide, which, in order to make thelayer IHOI'G'IJOI'OUS, I mix previously with some loose inert material. Instead of using pure benzoic sulphionide, the commercial article, sold under the name of saccharine/f which consists, mainly, of henzoie sulphionidc, may be employed; but as a considerable portion of this article is insoluble in the class of compounds cit-ed it can only be employed in those cases Where the finished product need-not be transparent or where it is possible to filter the mixture. The quantity of be-nzoic sulphionide which I comblue with any of these substances depends upon the purpose for which the mixture is to be used; but I find that when the composition is to be eaten the proportion of about three parts of benzoic sulphionide to one thopsand parts of the edible substance'is gen erally sufiicient, while for compositions which are to be masticated only a larger proportion, averaging one part of benzoic sulphionide to one hundred parts of the chewable snb st-ance,;is. necessary. I do not, however, restrict mys'elf'to any of these proportions, but alter them to suit the requirei'nents. of the-occasion.

In order to better show the bearing of my invention, I will explain the meaningv of theterm ingestible carbon compounds as used and understood in this specification, and also enumerate those special substanoesrfhich come within the scope of the limitation. insoluble in water, but soluble in bisulphide of carbon.

The term ingcst-ible carbon compounds comprises all. of those carbonaceous sub stances which are intended to be taken into the mm1t-h,thus includingthe majority of comestibles, internal medicinal remedies, and of substances to be simply chewed or masticated. The qualification insoluble in water, but soluble in bisulphide of carbon, however, restricts these substances to certain distinct grbnps-namely, to the oils, fats, waxes, resinous bodies, and paraffines, excluding thereby all saccharine, farinaceous, and albuininous bodies, as well as most of the n1edici nal substances.

The oils and fats comprise certain liquid and solid animal and vegetable products, which are insoluble in water, but dissolved by bisulphide of carbon, and are composed mainly of the glycerides of certain organic acids. The principal oils and fats to which I have reference are, olive-oil, almond-oil, ground-nut oil, cotton-seed oil, sesame-oil, poppy-seed oil, sunflower-oil, colza-oil, mustard-seed oil, niger-seed oil, caster-oil, lard, tallow, butter, oleomargarinc, and cod-liver oil.

The waxes c niprise certain solid sub stances originating from plants or insects, which are insoluble in water, but dissolved by bisulphide of carbon, and consist, mainly,

of various organic acids, both free and in combination with alcohol radicals other than glyccrinc. The principal waxes to which I,

have riiitercnce are beeswax, earnanba-wax, china-wax, and gapamwm.

The resinous bodies comprise certain liquid and solid substances of vegetable origin, which are insoluble in water, but (lissolred by bisulphide of carbon, and consist, mainly,

of various organic acids and hydrocarbons.

They are technically divided into several subgroups, of which the soft resins, oleorcsins, and india-rubber-likesubstances alone are of import in connection with this invention; The principal resinous bodies to which] have reference are rosin,spruce-gum, copaiba, balata, chicle, guttapercha, and india-rubbcr.

The paraffines comprise certain solid and semisolid substances which are insoluble in water, but dissolved by bisulphide of carbon, 1

and consist of one or more of the higher membersof ahomologous series of compounds that is known as the parailine series of hydrocarbons. The principal parafiines to which I have reference are parafiine, mineral was, i

and Vaseline.

Having thus described my invention, whatl claim, and desire to secure by Letters Patent, is-- As a new composition, the solution of henj zoic sulphionide, in thatelass ot ingestiblo carbon compounds which is insoluble in wat or,

but soluble in, bisulphidc of carbon.
